    Reproduction is a process through which organisms gives rise to there young ones which are same as there single parent or have mixed characteristics of there parents. Reproduction helps to maintain the continuity of a particular species.
    There are two ways in which organisms can reproduce offsprings:-
    1. Asexual reproduction- This is the process by which offsprings are produced without the fusion or production of gametes. Asexual reproduction takes place where there is only one parent. The offsprings are identically same as there parent and are called clones. Asexual reproduction is a simple and fast process.
    For eg:-
    Binary fission- In this process, a cell is divided into to and each cell contains a copy of a DNA. Eg- Amoeba.
    Fragmentation- In this process, the main organism splits and new individuals are formed from each half. Eg- planaria
    Sporogenesis- In this process individuals from the reproductive units called spores.
    Parthenogenesis- It is the process by which the bees gives rise to the young ones by the formation and development of eggs without the process of fertilization.
    2. Sexual reproduction- This is the process by which the male gamete which is the sperm and the female gamete which the ovary fuse together to produce the offspring. The offspring contains characteristics of both the parents hence are not exactly same as there parents. Sexual reproduction is a complex and slow process.
    Eg- in human beings,dogs etc.
    The organisms which can produce 2 distinct type of gametes are called anisogamous which contain the male gametes sperm and female gamete ovary. Eg- plasmodium, vertebrates.
    The organisms in which the gametes are identical are called isogamous species. Eg- chlamydomonas, algae etc
    There are many organisms that can reproduce sexually as well as asexually like hydra, jellyfish, yeast and many more depending on the conditions they are in.
